Sometimes filters aren't enough to limit a column of set values. Names, locations or any other arbitrary text don't benefit from filters and any workaround can feel a bit clunky.

It would be great using the same tooltip we use for filters and put a search field in it, allowing for arbitrary text to be searched in a certain column. This could be combined with traditional filters (particularly useful because you can filter by hidden values) for an all around table filtering.

I have taken a look at the code and it shouldn't be too hard to implement considering the way filters currently work. I would try it but I'm honestly swamped right now and don't have enough time to get it right.

Great job all around folks. This toolkit is amazing and very promising!
